What is Diamond Grinding?

Polished concrete is a craft that tends to be misunderstood. Often when people hear about polished concrete, they assume it is achieved through the application of a topical product or that it defines a cleaning process that makes the floor appear shiny. However, neither of these accurately describe the process of mechanically refined polished concrete. Polished concrete is a detailed, labor and skill-intensive process that requires highly specialized tooling and training to produce. One of the numerous tools required in this process is a grinder with diamond tooling.

Nowadays, most of the concrete grinding is performed by diamonds. This process is called as “diamond grinding”. Grinding concrete with diamond tooling is a mechanical process that renews worn or irregular concrete surfaces. It uses specialized tooling to produce a smoother surface and reduce concrete failures such as joint faults, warped slabs, and traffic wear. Due to the power needed to grind concrete, the diamond tools can quickly overheat during a wet grind process. Overheating is prevented by cooling the machine with water. However, this means a slurry is produced from the grinding and water excreted but the slurry is removed and disposed of. Dry grinding is also done with an air-cooled system. Both options can achieve the same desired result.
